In keeping with Piagetian theory, objective social reasoning seems to require the onset of formal operations ( 1 ) . However, the relationship between one form of social reaoning, e.g., open-mindedness ( 2 ) , and the highest stage of cognitive development, e.g., formal reasoning, is a much neglected area of research. This is true in spite of the fact that they both exemplify a systematic structure or network of formalized principles and emphasize structure over content. A relationship seems reasonable since openminded thinking depends on the interconnectedness of psychological systems as does formal reasoning, whereas closed-minded thinking, i.e., dogmatism, represents a compartmentalization, isolation, or incompleteness of these systems as in non-formal thinking. To examine the possible relationship between formal and open-minded reasoning, Rokeach's 40-item Dogmatism Scale (Form E. 1960) was administered concurrently with the How is your Logic? test (Form B, 1976)' to 59 college students at the University of Toledo and 420 students in Grades 7 through 12 at Lake Local Schools, Toledo, Ohio. The Dogmatism Scale required students to indicate their opinions about social and personal issues on a six-point Likert scale and the Logic test required students to construct and explain answers to 13 questions involving the mental operations of seriation, combinatorial reasoning, permutations, implication, and proportionally. The reliability coefficient ranged from .68 to .93 for the Dogmatism Scale ( 2 ) , and .71 €or this administration of the Logic test (W. M. Gray, formal communication, May, 1979). A one-way analysis of variance showed a significant difference across grade levels for both the Dogmatism and the Logic scores (Pa . r~ = 18.3, and P = 18.9, ps < .001, respectively) as well as for just the formal reasoning items of the Logic test (P = 19.5, p < .001). Mean scores at the highest grade, i.e., college, were 56.9 ( 8 1 maximum) on the Logic test and -29 ( 120 maximum) on the Dogmatism scale. The Dogmatism scores were significantly correlated but only at a low level with the Logic scores (M.30, p < .001) and also with the formal reasoning scores (-0.27, p < .001), indicating a reduction in closed-mindedness aod improvement in formal reasoning with increased age. At each grade, however, Dogmatism scores were significantly ( p < .05) and negatively correlated with both Logic and formal reasoning scores only at Grades 8, 9, and 12. Further, scores grouped as homogeneous subtests (using a Scheffk multiple-range test) indicated different patterns of age-related changes for the Dogmatism and formal reasoning measures. The present results indicate chat fully formal reasoning as well as openmindedness is not necessarily an eventuality even by college. Also, the pattern of scores on measures of both formal and dogmatic reasoning is not necessarily parallel at any particular grade nor for the age-related improvement that occurs across all grades. Obviously, further research is needed.
